If the allele for yellow peas is Y the allele for the contrasting trait green peas is?
y
What is the physical result of a combination of alleles?
Alleles are carried on genes so a combination of alleles results in a new offspring (baby).
Is it possible for 2 alleles to produce four phenotypes?
Yes which ever of the two alleles is dominant, then the phenotype will take the one of the dominant. they can be codominant, so in that case, you might be able to produce 4 phenotypes. it depends if the two alleles create 4
What is a trait expressed when two different genes for the same trait present?
If the two different genes include one dominant allele and one recessive allele, which is the heterozygous genotype, the dominant phenotype is expressed. For example, if R represents the red flower allele and r represents the white flower allele, the flowers would be red. If the trait is governed by incomplete dominance, then the heterozygous genotype (Rr) will produce an intermediate phenotype, such as pink.
What phenotype is produce by each of the following genotypes?
The genotype each offspring has is determined by the parents. They can be both homozygous dominant or are they heterozygous and homozygous(dominant or recessive)
What is it when the presence of two different alleles results in an intermediate?
When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.
Do all heterozygous pairs of alleles produce an intermediate?
No
Do all heterozygous pairs of allele produce an intermediate phenotype?
No
Dominance that occurs whenever the hybrid genotype produces a new intermediate phenotype?
When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.

What is the physical result of a combination of alleles?
Alleles are carried on genes so a combination of alleles results in a new offspring (baby).
How many different traits can these alleles produce?
A single pair of alleles would produce only one phenotype.
What genotype is produced by the phenotype B?
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.
How does incomplete dominance function at the molecular level?
One funcional allele is insufficient to produce the dominant pheontype. Both alleles are expressed as an intermediate of the alleles.
What do dominant and recessive alleles have in common?
Alleles are different types of a gene. Each gene controls a characteristic and they is usually a recessive allele and a dominant one. The main similarity is that they both control a certain characteristic!
What is the phenotype of all four offspring's?
Generally, if the parents are heterozygous and one allele is dominant over the other there are only 2 phenotypes and 3 genotypes. Parents Aa can produce AA, Aa and aa offspring. If the heterozygous individuals have an intermediate phenotype, then three genotypes and 3 phenotypes are possible. If 2 traits are being studied using heterozygous parents AaBb then the possible Genotypes are AABB, AABb, AAbb, AaBB, AaBb, Aabb, aaBb, aaBB, aabb which is nine genotypes. But there are 4 phenotypes. AABB AABb AaBB AaBb are phenotypically the same. aaBb, aaBB are phenotypically the same. Aabb, AAbb are phenotypically the same. aabb
